Calcium Chloride catalyzed Intramolecular Oxa Michael addition of 2’-Hydroxychalcone to Flavanone
An efficient cyclization of 2’-hydroxychalcone to flavanone using calcium chloride as a catalyst was developed. The scope of the reaction was studied with substituted 2’-hydroxychalcone and these chalcones was converted into corresponding flavanone in good yield. The merits of this method are inexpensive and easily available catalyst, easy workup procedure, avoid use of toxic solvent.
متن کاملNickel-catalyzed reductive allylation of aryl bromides with allylic acetates.
This paper highlights Ni-catalyzed allylation of electron-rich aryl bromides with a variety of substituted allylic carbonates using zinc as the terminal reductant, affording E-alkenes regioselectively in good to excellent yields by the addition of aryl to the less hindered allylic carbon. The electron-deficient aryl bromides and chlorides are also highly efficient coupling partners.

متن کاملPhosphine-catalyzed regioselective Michael addition to allenoates.
The first phosphine catalysed Michael addition of arylcyanoacetates to allenoates has been developed, and the β-selective products with a quaternary center were obtained in excellent yields. This unusual regioselectivity may open new opportunities to access interesting molecular structures.
متن کاملN-heterocyclic carbene-catalyzed aza-Michael addition.
Aza-Michael addition of amines, including aromatic and aliphatic amines, with α, β-unsaturated ketones was realized employing N-Heterocyclic Carbene (NHC) as organocatalyst, yielding β-amino ketones with up to 98% yield.
